Frontier Airlines, the eighth-largest carrier in the United States, has issued a stark warning that could affect millions of domestic passengers. In its second-quarter 2025 earnings report, the airline posted $929 million in revenue but a $70 million net loss, reported Plunge Daily.
In spite of the setback, CEO Barry L Biffle insisted results were within the company’s guidance and reaffirmed that Frontier is on track for profitability in 2026. However, Biffle, during the earnings call, made a blunt forecast. He was quoted in a Plunge Daily report saying that the aviation industry will be seeing continued reductions.
Why are airlines pulling back on flights?
Biffle explained that domestic air travel in the United States is no longer profitable for many carriers, once code-sharing and international routes are excluded, the report added. He said the supply is greater in comparison to demand and added that many domestic flights are currently operating at a loss. As a result, Frontier and other airlines are expected to scale back their US route networks.
The cuts will likely focus on less-popular travel days, off-peak times, and smaller markets.

United Airlines echoes the warning
Another report in The Street quoted United Airlines CEO Scott Kirby backing Biffle’s assessment. Kirby said that a ‘double-digit percentage’ of routes operated by many carriers outside of United and Delta lose money.
Kirby was quoted in the report as saying that the only way for the airlines to make a profit is by stopping flights to places that lose money. He added that route reductions are inevitable.
What will be the impact on travelers?
For passengers, these cuts could mean that they would have fewer flight time options, particularly during off-peak hours, reduced service to smaller airports, higher fares on remaining flights, and more crowded peak travel periods, the IB Times report stated.
According to the report, budget carriers like Spirit Airlines have already begun trimming less-popular flights. Travelers who typically book midweek or early-morning departures may soon find these options disappearing.
Frontier’s current position
Despite challenges, Frontier is expanding strategically, and it recently added 35 new routes and took delivery of fuel-efficient Airbus A321neos. The airline is focusing on the Eastern and Midwestern US, aiming for mid-to-high single-digit growth in revenue per available seat mile in the coming quarter, the Plunge Daily report added.
However, Biffle’s warning reflected a broader industry shift where the airlines are prioritising profitability over offering abundant route choices.

If these predictions hold, air travel within the country in 2026 and later could consist of fewer flights and possibly higher fares. Travelers are advised by experts to book early, to look for alternative airports, and to be flexible with the schedule.
The days of cheap domestic flights, particularly during the off-peak season, could be numbered.
FAQs
Why is Frontier Airlines cutting flights?
Frontier Airlines is cutting flights because many domestic routes are unprofitable due to oversupply and weaker demand, making it financially unsustainable to operate them.
Will other airlines cut flights too?
Yes. United Airlines and other carriers have signaled similar plans to reduce capacity on loss-making routes.
When will these changes take effect?
Gradual reductions could begin in late 2025, with more significant cuts expected in 2026.
Which flights will be affected first?
Off-peak routes, midweek departures, smaller airports, and less-popular travel times are most at risk.
